Board & Batten Siding for Edgemoor Homes
Edgemoor sits on the bluff above Bellingham Bay, and that setting cuts two ways for a home's exterior. The views and the shoreline exposure that make the neighborhood desirable also mean the siding on these homes deals with more direct wind and salt-laden air than a comparable house set back from the water. Add in the mature tree canopy that covers much of Edgemoor's older, established lots, and you've got two very different stress patterns hitting the same house depending on which wall you're looking at — a bay-facing wall taking wind-driven rain head-on, and a shaded interior wall staying damp for days after a storm because the tree cover keeps sun and airflow off it.
Board and batten is a popular choice in a neighborhood like this because the vertical lines suit both the older character homes and the newer construction mixed in among them. But it's also a profile with more seams per square foot than standard lap siding, which means every one of those seams is a place water can try to work its way in. On a bluff where wind and salt are part of daily weather, and under tree cover where moisture lingers, how those seams are built matters as much as which product goes up.
We install James Hardie fiber cement board and batten exclusively, and every fastening pattern, batten clearance, and flashing detail on an Edgemoor job is built around what this specific setting does to a wall over decades, not around what looks finished on install day.

What Edgemoor's Setting Asks of a Board & Batten Wall
Bluff-Top Wind and Salt Exposure
Homes closer to the bluff edge take wind straight off Bellingham Bay, and that wind carries salt with it. Salt-laden air accelerates corrosion on any exposed metal, and board and batten uses more fasteners per square foot than a standard lap profile because both the boards and the battens need to be secured independently. On these bay-facing walls, fastener spec — corrosion resistance, correct length, correct spacing — carries more weight than it would on a sheltered inland wall.
Mature Tree Canopy and Extended Moss Season
A lot of Edgemoor's charm comes from its tree cover, but that same canopy keeps shaded walls damp long after a storm has passed and the rest of the neighborhood has dried out. That kind of standing dampness is exactly what moss and mildew need to take hold, and a batten set tight against a board with no room to ventilate traps that moisture right where it can't escape — a slow path toward staining and softening at the seam that can take a couple of wet seasons to become visible.
A Mix of Older and Newer Homes, Different Starting Points
Edgemoor's housing stock spans decades, and an older home's wall assembly is a different starting point than a newer build's. On established homes, what's happening behind the existing siding — old flashing, aged house wrap, any water damage that's built up unnoticed over the years — has to be part of the plan before new board and batten goes up, not something discovered halfway through the tear-off.
Why Product Choice Matters More on This Profile
Board and batten amplifies whatever weaknesses a siding material already has, because there's more seam length and more exposed material edge for weather to work against. That's part of why we don't offer LP SmartSide, vinyl, Cemplank, Allura, primed spruce, or cedar board and batten. Those are legitimate products, and other contractors install them competently, but on a profile with this many joints, on lots that see direct bay wind and extended shade in the same afternoon, we standardized on one system we trust completely.
| Material | Behavior at Batten Seams | Fit for Bluff/Shade Exposure | Realistic Lifespan |
|---|---|---|---|
| James Hardie fiber cement | Dimensionally stable; doesn't swell or cup at the joint | Handles salt air and standing shade dampness without warping | 30+ years with proper install |
| LP SmartSide (engineered wood) | More sensitive to moisture at cut edges and fastener holes | Shaded, damp walls stress edge sealing over time | 15-25 years, climate-dependent |
| Vinyl | Can gap or distort at battens with temperature swings | Salt and wind exposure make hidden moisture harder to catch | 20-30 years, variable |
| Cedar | Absorbs moisture readily at every seam without regular sealing | Extended moss-season shade shortens the interval between resealing | 15-25 years with consistent upkeep |
James Hardie's fiber cement core doesn't expand and contract with moisture the way wood-based products do, which matters most on a profile built entirely from vertical seams. The factory-applied ColorPlus finish also means cut edges primed on site are the exception rather than the rule — unlike a field-painted material, where the whole wall's protection depends on paint holding up outdoors, under a tree canopy, year after year.
What a Correct Board & Batten Install Actually Involves
The finished look is simple — vertical boards, battens over the seams — but a correct install on a lot with mixed sun, shade, and wind exposure has more going on behind that surface:
- House wrap or weather-resistive barrier installed and lapped correctly before any siding goes up
- A drainage gap or rainscreen behind the siding so moisture that gets past the surface can dry out instead of sitting against the wall — especially important on shaded, slow-drying elevations
- Corrosion-resistant fasteners at the manufacturer's specified spacing, sized appropriately for bay-facing walls with direct salt exposure
- Battens set with the clearance Hardie's install spec calls for, not caulked tight, so the wall can shed water instead of trapping it
- Properly flashed and lapped transitions at windows, doors, corners, and the base of the wall, where a vertical profile meets a horizontal surface
- Assessment of the existing wall assembly on older homes before new siding covers anything that needs repair first
- Factory-cured ColorPlus finish preserved by cutting boards face-down and priming any field-cut edges before installation
Skip any one of these and the wall can look fine for a season or two. The problems that follow — staining at seams on shaded walls, corroding fasteners on bay-facing ones, soft spots where an old moisture issue was covered rather than fixed — take time to surface, which is exactly why they're easy for a rushed install to get away with until the homeowner is the one living with it.
Our Process for an Edgemoor Board & Batten Project
Walkthrough and Assessment
We look at each wall on its own terms — which face the bay and take wind and salt directly, which sit under tree cover and stay damp longer, and on older homes, whether the existing assembly shows any signs of moisture that needs addressing before new siding goes up. A single house in Edgemoor can have three or four different exposure conditions across its walls, and the plan should reflect that instead of treating every elevation the same.
Detailing the Plan Before Install Day
Batten spacing, corner details, and how the siding meets windows, trim, and rooflines all get worked out before crews start cutting material. On a profile with this many seams, deciding those details on paper first avoids field improvisation — which is usually where corners get cut on a job.
Installation to Manufacturer Spec
Every fastener, gap, and flashing lap follows James Hardie's published installation requirements for this region, not a generic national standard. That's what keeps the manufacturer's warranty intact and what keeps the wall performing the way it should for decades rather than years.
Final Walkthrough
We walk the finished job with you, cover what little maintenance board and batten actually needs, and make sure you know what to look for if you ever want to check the wall yourself down the road.
Why Hire a Crew That Already Works Edgemoor
Board and batten rewards familiarity with a specific setting, and Edgemoor's mix of bluff exposure, heavy tree cover, and older housing stock is specific enough that generic experience doesn't fully cover it. A crew that's worked this neighborhood through multiple wet seasons has already seen which bay-facing walls need extra fastener attention, how much clearance a batten actually needs when a wall sits under shade most of the day, and what to look for behind the siding on an older home before new material goes up. That judgment doesn't show up on a spec sheet — it's the difference between a wall that still looks and performs the same in fifteen years and one that's showing seam staining or fastener corrosion by year five.
Cost Factors for Board & Batten in Edgemoor
Board and batten typically runs more per square foot than standard lap siding, mainly due to the added material and the extra labor of fastening and detailing two layers instead of one. A few things move the price further on a given Edgemoor home:
| Factor | Why It Matters Here |
|---|---|
| Bay-facing vs. sheltered walls | Wind and salt exposure can call for upgraded fastener specs on the walls that face the water |
| Existing wall condition on older homes | Hidden moisture damage found during tear-off needs repair before new siding goes up |
| Tree cover and access | Mature landscaping can add labor for clearance, protection, and site access |
| Batten spacing and reveal | Tighter spacing uses more material and more fastening labor |
| Trim and window detailing | More openings mean more flashing and finish work around each one |
We'll walk your specific property and give you real numbers based on your home's actual exposure and condition, rather than a rough estimate off square footage alone — two Edgemoor homes of the same size can land very differently depending on how many of these factors are in play.
Getting It Right the First Time
Board and batten isn't a forgiving profile to redo. Because the battens cover the seams between boards, correcting a bad install usually means pulling battens, boards, or both, rather than a simple patch. That's part of why we treat the assessment and detailing phase as seriously as the install itself, particularly on a neighborhood like Edgemoor where bluff exposure, tree cover, and older wall assemblies all need to be accounted for before the first board goes up. Getting it right the first time costs a lot less than tearing out a wall that was rushed.
